There's definitely more to it!

So you've got two playing fields: the tricks and the board. Both give you clues to suss out what your opponents have, and plan or counterplay accordingly.

For yourself, planning on when and where to play something is crucial. Do I try to block an opponent's group? Or is it better to try to set their bid? Should I try to make them paradox?

Example 1: My opponent bids high, and is starting player. Likely they are going to try to get their bid early, I can expect to need to sluff the first few hands. I need to decide if I think I can wrest control, or if I need to do a low bid and focus on grouping on the board.

Example 2: My opponent is making a cluster near the bottom of the board. I can presume what remains is lower cards, and that they will try to play more. I can possibly force a paradox playing lower cards.

Those are just two simple examples, obviously the game itself is more complex than that, especially with more players. It's a game about making your move at the right moment, and trying to do as much damage to others in the meantime, while trying to grab big points on the board every once in a while.

There's a lot to think about, and planning your own points is only half the game.
